Don't amputate! Treat penile cancer with radiation therapy
Squamous carcinoma of the penis tends to be treated with a partial or total penectomy, often because urologists don't know that radiation therapy may be just as effective. Interstitial brachytherapy or external-beam radiation therapy should be considered as alternatives, according to Canadian researchers.

Infrared sensors track radiation treatment in India
An inexpensive automatic sensor device that halts external-beam radiotherapy treatment if a patient moves can result in more precise treatments, study results suggest. The device prevents unnecessary radiation exposure to normal tissue when immobilization devices are not utilized.

NetMeeting software aids oncologist/radiologist collaboration
U.K. researchers have found that off-the-shelf Internet conferencing software can help improve collaboration between radiologists and radiation oncologists in ways that sophisticated PACS software can't.

Breast ultrasound CAD performance varies in ethnic populations
A pair of new studies on a prototype breast ultrasound computer-aided detection (CAD) application has produced intriguing results. They indicate that the software's performance can vary based on factors such as the clinical environment in which it's used and possibly even the ethnicity of patients.

Hospitals look to regain market share in outpatient imaging
Hospitals that haven't established outpatient imaging centers have been losing market share to standalone imaging centers. But hospitals are getting a second chance in outpatient imaging thanks to the financial impact of the Deficit Reduction Act, which is hammering many independent imaging centers.

Biological 'fingerprints' help identify mislabeled chest x-rays
When patient images end up misfiled in PACS, the process of identifying them can be laborious and time-consuming. Now Japanese researchers say they've found a solution with an image-matching technique that uses biological "fingerprints" of posteroanterior chest radiographs to match unknown x-rays to prior images.

Outpatient imaging health predicted strong through 2013
Because the demand for diagnostic imaging services will continue to rise, the "state of the state" of outpatient imaging in the U.S. will remain positive over the next five years, an imaging consultant predicts. But providers will need to demonstrate the value of the services they offer to get a share of the pie.

Intrusion-detection testing finds network vulnerabilities
Many healthcare facilities don't recognize how easily minor changes can make their network vulnerable to intrusions, and facilities that outsource IT services have no guarantee of the quality of protection being provided. Penetration testing, as intrusion-detection audits are also called, identifies crucial vulnerabilities.

Epicardial adipose tissue on LDCT tied to cardiovascular mortality risk
By Amerigo Allegretto
Epicardial adipose tissue (EAT) on low-dose CT (LDCT) images is tied to higher cardiovascular mortality risk in lung cancer patients.

Epicardial adipose tissue (EAT) segmentation (shading) at noncontrast chest CT in axial orientation. Representative examples show EAT changes (ΔEAT) between baseline and two-year follow-up CT scans in participants who survived (typical changes) and increasing and decreasing EAT in participants who died.

Images in an 18-year-old man with recurrent dislocations of the right shoulder. (A, B) Unenhanced coronal, (C) axial, and (D, E) sagittal deep learning super-resolution threefold parallel imaging -- accelerated turbo spin-echo MRI scans were obtained at 3-tesla field strength. (A) Coronal T2-weighted fat-suppressed (FS) and (B) coronal proton density (PD)-weighted MRI scans show a nondisplaced superior labral tear (arrows). (C) Axial proton density-weighted fat-suppressed, (D) sagittal T2-weighted fat-suppressed, and (E) sagittal T1-weighted MRI scans show continuation into a nondisplaced anteroinferior labral tear (arrows). All seven readers correctly diagnosed the arthroscopy-validated findings. (F) An arthroscopic photograph shows the anteroinferior labral tear (arrow). Image and caption courtesy of the RSNA.

Maximum-intensity projection (MIP) images and axial and coronal PET/CT images of Ga-68 FZ-NR-1 and F-18 FDG both showed high uptake in lung metastases (arrow). (B) PET/CT images and nectin-4 IHC staining of patient 2. MIP images and axial and coronal PET/CT images of Ga-68 FZ-NR-1 showed high uptake in recurrence of right breast cancer after surgery (arrow), and those of F-18 FDG PET/MRI showed high uptake.
